I was hoping this problem would not resurface after I made every attempt to protect these Blind Spot Modules (Part # 22971842) from the elements this past summer. I very neatly covered them up with Gorilla tape and self-fusing silicone tape (see picture). I did this since these modules are exposed behind the rear tires and they have failed multiple times due to corrosion. I did not want to do anything permanent.
I was driving and the dreaded “Service side detection” came up again. When I tested them both sides are no longer working, they are just dead. In the past one side would go, then the other side would go. Keep in mind this car only has 77,000 KM on it (about 47,000 miles). Ironically today was the six-year anniversary of purchasing the car.
I brought it in and it says “Tech Cause: body code B101D ECU hardware left side detection module and harness damaged do to corrosion.” Apparently, I need a new harness. Total cost = $1,014.54!
They told me to call GM, to see if I can get the price down. I talked to a guy and he took my information and he is going to call the dealer. I called around 12:30 PM and never heard back as of writing this at 6:30 PM. I will be extremely surprised if GM will do anything to help at all.
The thing that annoys me most about this is the fact the general attitude is that once it is beyond its three-year warranty they are kind of like “that’s the way it goes, it is an old car”. Meanwhile my friends 2013 Nissan Altima with more miles on it has never had any modules or harnesses replaced. Sure, if this car was a 1973 I could see wiring harnesses rotting away due to age, but a six year old car?
Here is my history with the blind spot system on the car;
Dec-11-2014 (Right Side) 3-year warranty
Jan-22-2015 (Left Side) 3-year warranty
Feb-07-2017 (Right Side) $339.00 (Was able to talk down price)
Feb-09-2017 (Left Side) $226.00 (Was able to talk down price)
Feb-05-2018 (Right Side) 1 year GM part warranty
I know some might say “why do you not just leave it, that is just a luxury”. After reading many articles and forums, if you leave this problem too long eventually it will start messing up the entire electrical system causing a short. This can result in problems with electronics in the dashboard. Others might say “just have the system disabled and be done with it”. I asked the dealer that and according to them since it is a harness issue they cannot or will not do that.
I am seriously considering trading this car in for a more reliable Toyota. I don't care much for the looks of Toyota's, but at this point reliability is more important to me. Besides my 1994 Mustang is the looks car (which may I add gets the same mileage put onto it with far, far fewer problems). This Cruze has had multiple other issues since purchasing it in 2013, such as the transmission leaking. I truly believe this blind spot module issue cannot be corrected, and every year or two it is due for replacement.
I posted this for anyone that has this same issue. Also, I am interested in the comments.
